MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 423,604, dated March 18, 1890. Application filed July 1, 1889. Serial No. 316,199. (No model.)

To 00% whom it may concern.-

Be it known that I, HOWARD E. HARBAUGH, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and usefullmprovementsinMechanical Movements, of which the following is a specification.

- My invention relates to mechanism for producing an intermittently, rotary and oscillatory movement from a'driving-pulley driven continuously in one direction and it consists of certain new and useful features of construction and combinations of parts specially devised to that end, all of which are hereinafter fully described, and particularly pointed out in the claims.

Referring to the accompanying drawings, which form apart of this specification, Figure 1 is a front elevation of my improvement, having the parts thereof arranged to produce an oscillatory movement of the center or main shaft. Fig. 2 is a like View of the same, having the parts thereof rearranged to produce a rotary motion of the main shaft. Fig. 3 is a plan View of the machine as shown in Fig. 1. Fig. 4 is a horizontal section at line X X of Figs. 2 and 5. Fig. 5 is a rear elevation. Figs. 6, 7, and 8 are vertical sections at lines X X, X X and X X respectively, of Fig. 5. Figs. 9 and 10 are vertical sectionsat line X X of Fig. 3 of the upper portions of the pulleys there shown. Figs. 11 to 15, inclusive, are detailed views showing two cams,

which are intimately connected with the operations of changing the movement of the machine from rotary to oscillatory, and vice versa. These last-mentioned views also illustrate the diiferent positions assumed by the cams while performing their allotted functions and the parts co-operating therewith.

Like letters of reference indicate corresponding parts throughout the several views.

A is a frame for operatively supporting the Various parts of the mechanism, and may be of any suitable form and construction.

A is a tubular bearing in the frame A. A is a bearing projecting from the frame A. I A horizontal opening A extends through slots referred to are clearly shown in Figs. 9

pulley D the pulley F may be disengaged the bearing A and frame A to admit other parts.

A is a boss projecting from the frame A.

I A is a horizontal opening extending through the boss A and frame A.

B is a pinion provided with a revoluble sleeve B, which is mounted in the bearing A and serves as a bearing forsaid pinion.

O is a main shaft of the machine, and, is inserted through the pinion B and sleeve B, which form a bearing therefor.

O is a pinion fast to the shaft 0.

C is a beveled gear-wheel for transmitting power from the shaft 0, to which it is fast. This wheel isnot shown in Figs. 1 and 2, as it would hide the pinions there shown.

D is a pulley fast to the revoluble sleeve B.

D D are lugs for operating cams, to be described hereinafter.

E is a bushing, which is rigidly connected withthe shaft Q by clamping it against the shoulder 03 thereon by means of the'nut C.

E is an annular flangeprojecting from the outside of the bushing E and having radial slots E opening outward therefrom. The

and 10.

F is a pulley loose on the bushing E.

F is a detent located on the inner side of and parallel with one of the spokes F of the pulley F.

F is a stud projecting from the spoke F into a longitudinal slot F in the detent F.

v F is a spring .for actuating the detent F, which, when normal, connects the pulley F, through the bushing E, with the shaft 0, as shown in Fig. 9, except that the shaft 0 is not there shown; By inserting the pin F through the holes F F and F in the spoke F detent F, and one of the;spokes of the 9 from the shaft 0 and caused to connect with the revoluble sleeve B through said pulley D, as shown in Fig. 10. The outer end of the pin F has a handle formed thereon, by means of which the machine may be operated by hand, if desired.

, G is a carriage capable of lateral reciprocation, as indicated by the dotted lines Y in one end of the rod L.

Figs. 3, 4, and 5. Obviously the carriage might be arranged to reciprocate in any of the well-known ways, but I prefer to pivot it by means of the bolt G to the frame A.

G G are tubular bearings inserted through and rigidly connected with the carriage G.

H is a'sector-gear fast to the axle H, which wheel I and the collar 1 which is fast to the axle I I is a pin projecting from the gear-wheel I through the slot I in one of the spokes of the gear-wheel I. The connection shown evidently requires the gear-wheels I I to revolve together at all times.

The sector-gear H and gear-wheel I are connected with the carriage G through the tubular bearings G G and axles 1-1 1 and therefore participate in the lateral reciprocations of the carriage G, already referred to, the openings A A in the parts A A A freely permitting lateral reciprocation of the parts extending through said openingsv and their connections. 1 Y

J is a pitman, which is pivotally connected with both the sector-gear H and the gearwheel I by means of bolts J J K is a tubular bearing extending through and rigidly connected with the frame A.

K is a rocking sleeve inserted through the tubular bearing K, in which it may be oscillated. The end K of the rocking sleeve K is re-enforced by increasing the diameter thereof, and provided with a transverse bi.- furcated stud K, which has a cam K set and I secured therein by the rivet K K is a collar fast to the rocking sleeve K.

L is a rod inserted through the rocking sleeve K, wherein it freely slides.

L isa cam integral or rigidly connected with The cam L has a hole L therein, which admits a pin K which projects from the stud K The pin K compels the .camL to oscillate simultaneously with thecam K and at the same time allows it to slide back and forth with the rod L, to the end'of which it is fast.

The cams K L have two motions, asshown in Fig. 11, limited by the pins A", and move simultaneously. The cam L also has two motions independently of the cam K, as shown "in Figs. 12 and 15. the cam K is to reciprocate the carriage G, thereby intermittently meshing the sectorgear- H and gear-wheel I with thepinion G,

. according as it is desired that the main shaft 0 shall oscillate or rotate. The office of the The function of nal-reciprocating motions already mentioned, oscillating reciprocating motions synchronous and identical with the rocking sleeve K, with which it is connected through the, cam L and pin K Power is applied to the free end of the rod L for operating the cam L the rocking sleeve K, and the cam K connected therewith. The

necessary power and motions for operating the rod L may be imparted thereto through a pattern-wheel having operative connection with the free end thereof, or in any other suitable manner, and it has not been deemed necessary or desirable to show any particular mode of operating it.

In order to facilitate an understanding of the combined operations of the entire ma chine, the operations of the different sets of parts comprising the same will be given. Attention will first be directed to the movements of the carriage G and the parts producing those movements. Supposing the pulley D to be disengaged from the pulley F, the carriage G and the cams for operating the same to be in the positions shown in Figs. 1, 5, and 11, and the sector-gear H to be meshed with the pinion O, revolving the pulley D, and the lug D (see Fig. 13 will engage with the upper portion of the cam L and throw it and the cam K to the positions indicated by the dotted lines in Figs. 5 and 1]. and shown by solid lines in Fig. 12, the result of which operations will be to move the carriage G to the position indicated by dotted lines Y in Fig. 5 and shown in solid lines in Fig. 4, and mesh the-gear-wheel I with the pinion C. At the proper time thereafter the rod L will slide backward, carrying the'cam L to the position indicated by dotted lines in Fig. 12 and shown in solid lines in.Fig. 14. The next revolution of the pulley D will cause the lug D to engage with the lower portion of the cam L (see Fig. 14) and throw it and the cam K to the positions shown by solid lines in Fig. 11, except that the cam L is in contact with the cam K in Fig. 11, and indicated by the dotted lines Z in Fig. 15. The rod L then slides to its original position, carrying the cam L to the position shown in Figs. 11 and 13. The series of movements just detailed will leave the carriage G, the cams K L, and the rod L in the same positions as at the outstart, and the gearconcentric with the latter,-as shown in Fig.

1, or eccentric therewith, as shown-in Fig. 2,

but both gear-wheels, being connected by the pin I must necessarily always revolve together. With the sector-gear H meshed with I the pinion C, as shown in Fig. 1, power applied to the pulley D and transmitted through the sleeves .B, pinion B, gear-wheels II, and pitman J to the sector-gear II will oscillate the latter and the main shaft O-so long as the connections just enumerated are maintained. Permit the connections and application of power to remain the same as last stated except that the carriage is moved so as to cause the sector-gear H to unmesh from and the gear-wheel I to mesh with the pin; ion 0, as shown in Fig. 2, the main shaft 0 will then rotate as long as the connections and conditions just stated remain the same, and the sector-gear II will oscillate as an idler. As has alreadybeen stated, power applied to the pulley D will oscillate or rotate the main shaft 0, according as the pinion O' is meshed with the sector-gear H or gear-wheel I. Power applied to the pulley F while it is connected with the main shaft 0, as shown in Fig. 9, will also cause the latter to rotate; but an oscillatory movement of said shaft 0 cannot be produced by applying power to, the pulley F, as said pulley must participate in all the oscillatory movements of the main shaft 0. There is, however, an ad vantage to be gained in driving the shaft 0 by means of power applied to the pulleyF when rotary motion is required, for while the periphery of the gear-wheel l and the pinion C are as three to one a complete revolution of the gear-wheel 1 produces, when transmitting motion through the pitman J and sector-gear H, but two oscillatory revolutions of the pinion O and its shaft C, while the same speed transmitted directly from the pulleyF to the shaft 0 would rotate it three times. The pinion O, sector-gear H, and gear-wheel J are so adaptedandarranged with referenceto each other in point of speed that either of the two latter'may engage with and disengage from the former while the machine is in full operation, the sector-gear when unmeshing continuing its engagement with the pinion until the gearwheel I is sufliciently meshed therewith to propel it, and vice versa. the machine are thereby rendered constant,

and alternately or intermittently rotary and oscillatory movements may be obtained from the main shaft 0, at the will of the operator. Obviously the pinion 0' might be arranged to travel between the sector-gear and gear-Wheel I and alternately mesh with the sameand produce like results without departing from the spirit and scope of my invention. Obviouslya gear-wheel or other equivalent toothed device might be substituted for the sectorgear H without changingthe character of my invention. The oscillatory and rotary motions of the main shaft 0 may be transmitted to any suitable mechanism through the beveled gear-wheel C 7 This machine may be used whenever intermittently oscillatory and rotary movements The movements ofall three of said gears being combined substantially as and for the purpose specified.-
